MarShield Lead Lined Plywood

MarShield’s plywood is laminated with sheet lead that is designed to cover necessary surfaces or walls in a room requiring radiation shielding. It is affixed to surfaces or walls ensuring a continuous layer of sheet lead, under the plywood, to a specified height. It is used in new construction or shielding upgrade/renovations for P.E.T and other types of diagnostic imaging rooms and to fill the void between lead-lined drywall and interlocking lead bricks. MarShield Lead-Lined Plywood is available in 5/8” to 3/4” in thickness with pure lead sheets of thickness 1/16” to 1/2′ factory laminated to it. All of MarShield's Lead lined plywood is fire rated and encompasses a layer of lead affixed to the surface of fire retardant plywood conforming to AWPA U/T1-16 Sec H. (fire retardant treatment standards). Pure lead sheet meeting Federal Specification QQ-L-201 F, Grade C and ASTM B749-03, Type L51121 is factory laminated under pressure to the plywood panel. Lead-laminated to plywood is applied in 48” widths on equal plywood widths up to 96” lengths. 2” wide batten strips can be supplied to cover all joints where applicable. Lead-lined plywood is typically recommended for heavier lead shielding requirements, usually when the lead shielding exceeds 1/8” thick. Lead-lined plywood at these thicknesses becomes very heavy to handle in full sheet form (4’ x 8’). MarShield recommends having us cut the lead-lined plywood into widths that are equal to your on-site stud dimensions (e.g. 12” or 16”). This will make the lead-lined plywood much more manageable for the installer.
